Social distance modulates outcome processing when comparing abilities with others

Social comparison occurs when individuals evaluate themselves in comparison with others. Social distance can influence the effect of social comparison. Using event-related potentials, this study examined how social distance affects the time course of outcome processing when individuals compare themselves with others in terms of ability. Participants were asked to perform a dot estimation task with a friend and a stranger. The results showed the effect of social distance on the N1, feedback-related negativity (FRN), and P300, such that the N1 and P300 were greater for the outcome when pairing with the stranger than when pairing with the friend, whereas the FRN was more negative for the outcome when pairing with the friend than when pairing with the stranger, suggesting that participants allocated more attention resources to the stranger's outcome during the early, automatic (the N1) and later, controlled processing stage (the P300). In addition, the FRN was sensitive to the valence of both self- and other-outcomes, and the FRN valence effect of self-outcome was modulated by friends' outcomes but not by strangers' outcomes, indicating that at the semi-automatic processing stage, closer social distance increases the likelihood of individuals being affected by the comparison targets. These results suggest that when comparing with others in the ability dimension, social distance plays a different role in different stages of outcome processing. At the primary stage of outcome processing, individuals are more likely to compare with close others in the ability dimension.

Automated summary

Social comparison is influenced by social distance, with closer friends having a greater impact on outcome processing compared to distant strangers. The study showed that individuals allocated more attention resources to the stranger's outcome during both the early and later processing stages, indicating a different role of social distance in different stages of outcome processing.
